Versioning & Governance

In short

Someone changes the button radius on a Friday, and on Monday three apps look broken. Versioning and governance decide who can change what, how it's checked and how teams find out.

Deciding how changes to shared components get proposed, reviewed, and rolled out — without governance, a design system tends to drift out of sync between design and code over time.

The jaadu presents a paint sample to a small committee sitting around a table near a society gate.

Think of it like this

Rules change at the housing society

Nobody repaints the society gate on their own. A member proposes it, the committee discusses it, a notice goes up, and then the work happens. Design systems need the same: a proposal, a review, a release note.

How a change gets into the system

Product team

DS team

Library

Proposal: icon button

1/4A product team needs something new and writes a short proposal with the use case.

The big ideas

What you need to know

Semantic versions

MAJOR.MINOR.PATCH: patch fixes bugs, minor adds features, major means something might break.

Changelogs matter

Every release lists what changed and what teams need to do. No surprises.

Clear ownership

Decide who reviews and approves changes. Without owners, either nothing changes or everything does.

Easy to contribute

A simple proposal template lets product teams ask for changes instead of building their own copies.

A tiny changelog. The version number alone tells teams how careful they need to be when updating.

Save yourself the pain

Common mistakes

Oops

Silently changing a component that dozens of screens use.

Do this instead

Release it with a version and changelog, and warn teams early for breaking changes.

Oops

Making the contribution process so strict that nobody uses it.

Do this instead

Keep proposals short and reviews quick. Otherwise teams build workarounds outside the system.

Your mission

Write a proposal and a changelog

~20 min

Quick check

You rename a component property, so existing screens will need updating. Which version bump fits?
